Dan Petro, a security analyst for the Bishop Fox IT consulting firm, built a proof of concept device that’s able to hack into any Google Chromecasts nearby to project Rick Astley’s “Never Gonna Give You Up,” or any other video a prankster might choose.

According to a blog post written by Petro (via TechCrunch), the “Rickmote,” which is built on top of the $35 Raspberry Pi single board computer, finds a local Chromecast device, boots it off the network, and then takes over the screen with multimedia of one’s choosing.
